1. Imagine a bug crawling along the circle from 0 to 2\pi . As the bug walks along the circular path, its distance above or below the ground changes. (We consider distance below the ground to be negative.) After traveling (\pi )/(12) radians, the bug is approximately 0.25 units above the ground. After (\pi )/(6) radians, the bug is 0.5 units above the ground etc.
2. Generate the bug's path using spaghetti.

a) For a given angle, place a piece of uncooked spaghetti at the corresponding radian measure on the unit circle perpendicular to the "ground" (i.e.,the x-axis).

b) Next, break off the spaghetti where it touches the ground.

c)Then, use a piece of tape or glue to attach the spaghetti piece to the graph.

d) Do the same thing for cosine. This time you'll be measuring the horizontal distance between a point on a circle and the y-axis.

Please just draw the spaghetti graph so I can teach my son
